    Abstract: The invention provides a spark generator for generating a spark for optical emission spectroscopy (OES), wherein the spark has a current waveform comprising a first modulated portion which comprises a plurality of relatively high current and high gradient peaks of variable amplitude and/or inter-peak duration and a second modulated portion of relatively low current and low gradient which is substantially without modulated peaks. The spark is preferably generated from two or more programmable current sources. The invention also provides an optical emission spectrometer comprising the spark generator and a method of optical emission spectroscopy using the spark generator.

    Abstract: Vacuum ultraviolet radiation detection apparatus (10) comprises a radiation detector (30) in a chamber (12). The detector (30) receives ultraviolet radiation from a radiation source (36). The chamber is evacuated using a dry vacuum pump (18) to a relatively poor vacuum of no less than 5 Pa. UV transparent gas is supplied from a gas supply (26), into the chamber (12) at a relatively low flow rate (around 0.1 litres/minute) so as to provide an overall pressure in the chamber (12) of between 100 and 1,000 Pa. The use of a relatively inexpensive pump coupled with a lower gas flow rate provides significant cost savings.

    Abstract: Characteristics of a flame within a turbine or burner are determined based upon ultraviolet, visible, and infrared measurements of the flame. The measurements include a measurement of the amplitute of frequency bands that are indicative of an efficient combustion process, such as those that increase when the flame temperature increases. The measurements also include of the amplitude of frequency bands that are indicative of an inefficient combustion process, such as those that do not vary, increase a relatively small amount, or decrease when the flame temperature increases. The temperature of the flame may therefore be determined accurately, to facilitate efficient operation of the turbine or burner while minimizing polluting emissions. A fiber structure, suitable for remote location of sensors and processing equipment passes energy for several spectra by providing a hollow core that passes infrared energy, in combination with a core of visible-transmissive material that passes visible or ultraviolet energy. Contaminants in the turbine or burner are detected, and a degree of contamination measured, by detection of energy levels for particular wavelengths associated with a respective contaminant.
